Procurement Notes

Verify the specific suffix 'TDBVRQ1' matches the required SOT-23-6 package and automotive grade designation. Confirm that the AEC-Q100 qualification aligns with your project's reliability requirements. Ensure the 1.2 A output current capability meets the load specifications. Check for any specific storage or handling instructions related to moisture sensitivity levels before assembly.

Selection Notes

Select this component when an automotive-certified LED driver is required for backlight applications. It is suitable for designs needing a compact SOT-23-6 footprint and integrated 1-Wire control. Consider the 1.2 A switch current limit and 1.2 MHz frequency for inductor selection. Verify compatibility with the system's input voltage range and PWM dimming requirements.

Part Context

This part belongs to the Texas Instruments TPS61165 series of high brightness white LED drivers. It shares core functional characteristics with other variants in the family but is distinguished by its automotive qualification (Q1) and specific SOT-23-6 packaging. The series is designed for efficient current regulation in boost converter topologies.

Replacement Considerations

Direct substitutes include other parts within the TPS61165 family such as TPS61165DRVR or TPS61165DBVT, provided the package type and automotive grade requirements are compatible. Verify pinout and electrical parameters match before substitution.
